David X. Cohen is an executive producer, show runner with Matt Groening and writer for Futurama. Although he was born David Samuel Cohen, he changed his middle initial in order to register with the Writers' Guild. The Guild has a rule that no two members may have the same name, and there was already "some jerk" registered with the name "David S. Cohen". He chose the "X" because it sounded more science-fictiony.

Although usually not credited, he is responsible for "perfecting" most of the scripts for each episode. He also wrote (and sung) the music for Molten Boron, and designed one of the robots in the robot strip club.

Characters Voiced

Although David X. Cohen has not officially voiced any characters, he does do a lot of temporary voice work (which can still be heard in some animatics). He has also been told that he has a robotic voice. Because of this, he was persuaded to try out for the part of Bender, but claims he couldn't remember how to do his own voice.
